Safety glasses

ABSTRACT

In safety goggles, in particular industrial safety goggles, comprising a curved sight piece and a soft frame between the sight piece and face contact area, it is provided that the frame is designed in the way of a bellows frame, having at least one fold.

[0001] The invention relates to safety goggles, in particular industrialsafety goggles, comprising a curved sight piece and a soft frame betweenthe sight piece and a face contact area, wherein the frame is designedin the way of a bellows frame, having at lest one fold.

[0002] Safety goggles of the generic type are known from DE 11 93 639B1.

[0003] It is an object of the invention to embody safety goggles thatenable the frame and face contact area to be optimally adapted to auser's anatomy, thus ensuring high convenience of wearing and optimalsafety.

[0004] According to the invention, this object is attained in that theframe encompasses the top of the sight piece, leaving an airing gap.

[0005] A fold or several folds of this type, which are known per se,produce great flexibility, creating high convenience of wearingaccompanied with a shock absorbing crumple zone that adaptsautomatically to anatomic requirements, with the fold or folds beingpreferably designed to encircle the entire sight piece. This providesfor total protection to all sides against any penetration of light,particles and splashes.

[0006] The airing gap according to the invention ensures that there isno direct passage between the outside and interior of the goggles, butnevertheless excellent airing conditions.

[0007] Provision may further be made for the lateral ends of the sightpiece to reach over the frame laterally, with airing holes beingprovided in this area between the sight piece and frame, which willstill further improve the airing conditions. The sight piecesimultaneously works as a cover for the airing holes.

[0008] Preferably, head strap clasps are lockable into place on thelateral ends of the sight piece. This design works to advantage as suchas well as in combination with a bellows frame, replacement of the sightpiece thus being easily possible and the sight piece itself being ableof assuming a kind of load-bearing function. A head strap is fastened tothe head strap clasps in a manner known per se.

[0009] This design also offers the possibility of ease of handling byautomats during manufacture.

[0010] By advantage, the approximately vertical lateral edge of thesight piece forms a locking projection for snap-engagement with the headstrap clasps, the locking projection cooperating with a correspondinglocking recess on the head strap clasp.

[0011] In the vicinity of the airing holes between the frame and thelateral ends of the sight piece, provision can be made for spacers whichwill keep the airing holes free even when the sight piece is pressedagainst the frame under tension by the head strap.

[0012] For greater flexibility, the lateral ends of the sight piece maybe slit on both sides of the locking projection.

[0013] Additional locking projections may be provided in the vicinity ofthe top and bottom edge of the sight piece.

[0014] Details of the invention will become apparent from the ensuingdescription of a preferred embodiment, taken in conjunction with thedrawing, in which:

[0015]FIG. 1 is a perspective view of a pair of safety goggles accordingto the invention;

[0016]FIG. 2 is a sectional view on the line II-II of FIG. 1;

[0017]FIG. 3 is an elevation of the sight piece, with a head strap clasplocked in place on the right;

[0018]FIG. 4 is a plan view of the sight piece of FIG. 3;

[0019]FIG. 5 is a sectional view on the line IV-IV of FIG. 3;

[0020]FIG. 6 is a perspective partial view of the pair of safety gogglesfrom inside; and

[0021]FIG. 7 is a partial plan view of the area, seen in FIG. 6, of thepair of safety goggles.

[0022] As seen in the drawing, a pair of safety goggles 1 comprises aone-piece continuous, curved sight piece 2 and a soft frame 3.

[0023] The rigid, inherently stable sight piece 2 supports the frame 3,which is mounted on the sight piece in a manner known per se by way ofkeyhole notches 4. Only one of these keyhole notches is plotted in FIG.3, the rest being roughly outlined by marks.

[0024] The frame 3 is joined to the sight piece 2 in the vicinity of thetop edge 5 thereof in such a way that an air gap 6 is left free that iscovered by the lowered outer edge 7 at the front of the frame 3.

[0025] As seen in particular in FIGS. 1 and 2, the frame 3 forms sort ofa bellows frame, correspondingly comprising several folds 8, which helpsaccomplish great flexibility and adaptability so that the face contactarea 9 will always fit a user's face tightly and nonethelessconveniently regardless of the specific anatomic requirements.

[0026] In the vicinity of the bottom edge 10 of the sight piece 2, theframe 3 encompasses the sight piece 2, having positive fit.

[0027] As seen in FIG. 5, the top of the sight piece 2 has a projection11 that stands out to the front. This projection 11 serves for holdingthe frame 3 and simultaneously works as a spacer for the production ofspace between the top of the sight piece 2 and the frame 3, forming anairing gap. For this effect still to be increased, provision can be madefor additional knobbed spacers in the vicinity of the projection 11and/or for one or several recesses in the sight piece which will howeverbe covered to the front by the frame.

[0028] In the vicinity of the lateral ends 12, the frame 3 is providedwith airing holes 13 which are covered by the lateral ends 12 that arebent at 14 in discontinuity of the curved sight piece so that neitherlight nor particles nor splashes are admitted to the inside through theairing holes 13.

[0029] In this area, the frame is provided with knobbed spacers (notshown) which prevent the lateral airing holes from being shut whentension is exercised on the sight piece by the head strap.

[0030] As seen on the left in FIG. 3, two slits 15 at the lateral ends12 form a flexible tongue 16 that is provided with a locking projection17 in the vicinity of the vertical outer edge.

[0031] Head strap clasps 18 can be locked on to the lateral ends; one ofthem is shown on the right in FIG. 3. The head strap clasps 18 have alocking recess 19 with which to snap-engage the locking projections 17.Additionally, projections 22 may be provided in the vicinity of the topedge and bottom edge of the lateral ends of the sight piece 2,snap-engaging with corresponding recesses of the head strap clasps 18(not shown). By advantage, the locking recesses 19 have the shape of awidening (see FIG. 3 on the right) of slots 20. For replacement of thesight piece 2, the locking projections 17 only have to be pushed downfrom outside so that they disengage from the locking recesses 19.

[0032] The head strap clasps 18 are provided with slots 20 through whichto pass a head strap 21.
